DOOR.

Application filed March 25, 1921. Serial No. 455,684.

T 0 all whom-it may concern:

Be it known that 1, JOHN D. Korma, a citizen of the United States, residing at lV'ic'hita, in the county of Sedgwick and State of Kansas have invented certain new and useful Improvements in Doors, of which the following is a specification.

This invention relates to doors and has for its object the provision of means whereby an ordinary paneled door may be arranged to serve the purpose of a screen door whereby to avoid the necessity of employing an additional door to provide ventilation and resist the entrance of insects during warm weather. Another object of the invention is to provide means whereby, when the door is in closed position, a view of the interior of the building will be prevented and another object of the invention is to provide means whereby a door which forms a screen door in its closed position may. be automatically set;

carried by rods 8 extending'across theirends A further ob-- to cover the screen and economize space as ject of the invention is to provide means whereby the act of opening or closing the parts. Other objects of the invention will appear incidentally in the course of the fol- N 1 ing ends with intermeshing seg'irrenta gears or racks 11. Itwillthus'be read-ily'unden lowing description. I In the accompanying drawmgs Figural is an elevation of a door having my invention applled thereto and show ng v mg thesame relative position attire opposite thedoo'r in its closed position;

door opening below said bar. In carrying out my invention, I remove from the door the ordinary solid panel and substitute therefor a screen panel consistingof a reticulflted body or section of wire netting 5 panels.

Fig. 5 is an enlarged view partly in sec tion and partly in end elevation; Fig; 6 is a horizontal section showing an-j other form of the invention; a

'Fig. 7 is a tra'nsverse section on the line having'i'ts edges within a frame 6 which is adapted to set in the channel provided in the stiles and the rails for the usual panel. This frame may be of anyconvenien t construction and consists of similar plates or open frames 7 of thin wood or sheet metal fitted againstthe opposite sides of the netting 5 around all the edges thereof, and the upper end of the frame should be wider'thanthe other portions thereof, as shown in Fig. 2,s'o that when thesw-inging cover panels 7 are lowered the said upper end of the frame'will'c'ut-off inspection through the space between the upper rail and the upper end of said panels.

i'lhe panel 7 will preferably bea wooden plate of substantiallythe-"same dimensions as theordinarypanel which was removed to permit the] insertion of the screen panel and the said cover panel is duplicated upon the outer and inner'sides of the door, as shown clearly in Fig. 2. These cover panels are and fitti-ngin eyes or bearings 9 upon. the The ends of the rock 'shaifitsare fixed to cranks or levers 1T0 which are "mounted for swingingmovemen't upon the stiles ofthe door, as showuinost clearly in Fig. 4, and are provided at theirinner'meet- Upon the upper an 4 on the'inner ea of the do'orQI secure brackets 12 and extending between said brackets are the guide rods 13.

A worm or screw 14 is journale'd at its lower end in the lower bracket Band has its upper "end rotatably fitted in and extended through the upper bracket, while a sliding nut 15 has its ends fitted upon the guides 13 and its central portion. formed with an internally threaded bore to engage the said screw ,or wormwhereby, when the screw is turned, the nut will becaused to. move upwardly or downwardly. Motion is imparted to, the screw by a segmental gear or rack 16 which is secured rigidly to the transom bar 2 and extends therefrom into the room" concentric with th hinges of the door. The teeth of this rack are formed on the concave edge thereof and mesh with a pinion 17 fitted upon the upper extended end of the worm or screw 14 so that as the door is swung upon its hinges the pinion will be caused to ride over the rack and will be thereby rotated and will impart its motion directly to the worm or screw. A lug or car 18 is formed on the nut 15 and to the said lug or ear, I pivotally attach the upper end of a link or pitman 19 which has its lower end pivoted to an arm 20 secured rigidly to and projecting from the panel 7. Assuming the door to be closed and the covering panels in the position shown in Fig. 2, if the door be opened, the pinion 17 riding upon the rack 16 will rotate the worm or screw 14; so that the nut 15 will be caused to ride upwardly thereon and this motion panels will be applied or converted in such manner that they will swing about the pivotal mountings of the cranks 10 as centers and will be thereby caused to assume positions close upon thescreen and within the panel opening of the door. The'door may, consequently, be swung back close to a wall without any interference from the covering panels and the parts connected therewith,

When the door isagain moved to closed position, a reverse motion will be imparted to the nut 15 and the elements connected therewith so that the panels will be automatically returned to the position shown in Fig. 2,

thereby permitting a circulation of air through the screen 5. in an obvious manner.

The screen-carrying frame will prevent passers-by obtainlng a direct vlew into the room which is entered through the doorway,

but it is possible that obliquely directed glances might view objects or persons in the room. To avoid this observation which is frequently undesirable, I provide a flexible fabric curtain 21 which is disposed along the center vertical line of the screen 5 and is attached thereto and has its outer edges at tached to the respectively adj acentpanels 7 vlVhen the panels are moved in close against the-screen, this curtain-will collapse or fold so that it will be housed between the panels and the screen without limiting the movement of the panels and without causing them to project unnecessarily beyond the vertical planes of the door. As the panels, however, are extended this curtain will, of course, be

drawn out and assume a position transverse to the screen 5, as will be readily understood and asshown in Fig. 3.

In F igs. 6 and 7 I have shown another embodiment of the invention which 'may sometimes be preferred. The operating mechanism in thisembodiment of the invention is the same as that shown in the previously described form of the invention and the screen-carrying frame 6 may be of the same construction as that previously described, the screen 5 being held therein, as shown. The frame 6 is set in the stiles 3 and in the rails of the door in the manner previously described and I also employ the rods 8 with cranks 10 pivotally fitted upon the stiles and provided with intermeshing gears. The panels, however, in this form of the invention are mounted to swing horizontally instead of vertically and to this end I secure along the vertical center of the screen dividing bar 22 which is composed of two similar sections secured against the opposite sides of the screen. To each edge of each section of this bar, I secure by hinges 23, a panel 24 which is imperforate. Each panel, when in closed position, will fit against the screen and between the edge of the bar 22 and the respective door stile. At the free edge of each panel, I provide a loop or slotted bracket 25 in which the rod 8 plays and to thatupper rod 8 which is at the inner side of the door I connect the lower end of the link or pitman 19, a coupling rod 26 connecting said shaft with the shaft below it. It will now be readily seen that when vertical movement is imparted to the pitman 19, the rod 8 to which its lower end is attached will be caused to swing about its pivotal mounting upon the door stiles and this piv- V otal movement of the rod acting through the loop or slotted bracket 25 will cause the panels 24 to swing horizontally and thereby cover or uncover the screen accordingto the direction of movement. In this form of the invention, the curtain 21 is unnecessary inasmuch as the bar 22 accomplishes the results sought by the use of said curtain and the said bar also serves to reinforce the screen and prevent buckling orcollapse of the same. I

It will be readily noted that my improved mechanism is very compact and will operate automatically so thatwhen the door is in closed position, the-screen will be uncovered and fresh air will be admitted to the room -while the gaze of curious passers-by is ob- 'structed.

screen will be covered and the parts will be When the door is opened, the

door, and means operable by movement of the door for uncovering the screen as the door is closed and covering the screen as the door is opened.

2. The combination of a door having a screen panel therein, a cover for said panel mounted upon the door, a frame binding the edges of the screen and arranged to prevent observation through the screen around the edges of the cover, and means'for swinging the cover from the screen as the door is closed and swinging the cover to the screen as the door is opened.

3. The combination of a door, a screen panel fitted in the door, covering panels mounted for movement at opposite sides of the door to and from the said screen panel, means for operating said covering panels as the door is opened or closed, and means for obstructing observation through the screen panel and between the covering panels.

4:. The combination of a door, a screen panel fitted in the door, a covering panel, rods pivotally mounted upon the door and operatively engaged with said covering panels, and means for imparting a swinging movement to the rods as the door is opened or closed.

5. The combination of a door, a screen panel therein, a covering for said screen panel, a slide mounted upon the door for vertical movement above the screen panel, operative connection between said slide and the covered panel, and means for actuating said slide as the door is opened or closed.

6. The combination of a door, a screen panel therein, a cover for said screen panel mounted upon the door, a screw mounted upon the door above the screen panel, a nut mounted for sliding movement upon said screw, a link connected with said nut and with the door, and means above the door for rotating said screw as the door is opened or closed.

7. The combination of a door having a ventilating panel therein, a cover for said panel mounted upon the door to move toward and from the said ventilating panel, a screw mounted upon the door above the said panel, guides on the door at the sides of the said screw, a nut fitted upon the screw and slidably engaging the guides, a link pivoted to said nut and operatively 0011- nected with the cover, and means-for rotating said screw as the door is opened or closed.

In testimony whereof I aflix my signature.
